Raspberry plant named ‘PBBrasp1351’

ABSTRACT

The present application relates to new and distinct cultivar of primocane-fruiting raspberry named ‘PBBrasp1351’. The new variety reliably provides balanced heavy crop load on both primocanes and floricanes, with large, glossy, conic fruits of unique peach-yellow color, with loose adherence to the receptacle and which maintain size throughout harvest. Plants possess high vigor and produce high numbers of spawn. Improved resistance to yellow rust ( Phragmidium rubi - idaei ) and field tolerance to Raspberry Bushy Dwarf Virus (RBDV) and  Phytophthora  root rot has been observed.

Latin name of the genus and species of the plant claimed: Rubus idaeusL.

Variety denomination: ‘PBBrasp1351’.

BACKGROUND AND SUMMARY

The new primocane-fruiting raspberry cultivar designated as‘PBBrasp1351’ is described herein. Botanically known as Rubus idaeus L.,this new variety resulted from a hand-pollinated cross of female parent‘Pacific Gema’ (U.S. Plant Pat. No. 28,080), a patent-pending releasefrom the same program, and the unpatented male parent ‘1108’.Pollination occurred in April 2012 and seeds from this controlled crosswere subsequently harvested, cleaned, germinated, and established asseedlings in spring 2013 in Watsonville, Calif., Santa Cruz County, USA.

‘PBBrasp1351’ was first identified in a substrate block, where seedlingshad individually been planted into 3 liter pots, in September 2013 inWatsonville, Calif. This selection was first propagated asexually bycrown division (of the original potted mother-plant) in autumn 2013 inWatsonville, Calif. The crown on the original plant was parted intobasal cane pieces (approximately 15 cm long) with root attached andplanted into soil, in a selection plot elsewhere on the farm, resultingin a 10-fold increase in plant material. Harvest and postharvest datawere collected from this larger plot of ‘PBBrasp1351’ for two years,from 2014 through 2016.

In January 2014, additional root pieces from the original mother-plantwere planted into an on-site greenhouse. Two actively growing etiolatedshoots were forced from roots, transplanted and potted. Onceestablished, these shoots were sent to Lafayette, Oreg., USA, wherevegetative material was explanted and established in vitro formicropropagation. Subsequent asexual propagation was done on-site inWatsonville, Calif. and, along with tissue-cultured plantlets,‘PBBrasp1351’ was evaluated extensively over the next several years forperformance and genetic stability.

The present cultivar, ‘PBBrasp1351’ offers many advantages over theexisting, patent-pending cultivar and red-fruited maternal parent,‘Pacific Gema’ (U.S. Plant Pat. No. 28,080) and the yellow-fruitedpaternal parent ‘1108’. The most distinct characteristic ‘PBBrasp1351’is the color, which is unlike either parent. ‘PBBrasp1351’ has anintermediate color, with peach-colored overtones and yellow-coloredundertones. Often, berries of ‘PBBrasp1351’ appear to be two-tone, whichis unique for raspberry. The unique color offers significant advantagesto marketers who seek methods to distinguish commodity products. Averagefruit size of ‘PBBrasp1351’ is considerably larger than both parents.Berries detach easily from the receptacle, which is similar to parent‘1108’, yet much easier than ‘Pacific Gema’. Fruits of ‘PBBrasp1351’ arebroadly-conic in shape (versus the narrow conic shape of ‘Pacific Gema’and ‘1108’). Yield of ‘PBBrasp1351’ is also much greater than ‘PacificGema’ and ‘1108’, on average, due to its higher vigor and larger fruitsize. The ease of fruit detachment and improved yield offers significantadvantages to growers, who require fast picking speeds and lighter fruitcolor, combined with glossiness which helps to extend shelf life of thefruit (by appearing to stay fresher for a longer period of time). Thelarger, broadly-conic berries help growers fill baskets more quickly,leading to increased harvest efficiency. Root vigor, subsequent canevigor, and floricane budbreak for ‘PBBrasp1351’ is superior to ‘PacificGema’ and ‘1108’.

In contrast to the unpatented male parent ‘1108’, the cultivar issignificantly greater in vigor, plant fitness and offers larger fruit.In particular, the amount of suckers that ‘PBBrasp1351’ produces istwo-fold of its paternal parent. This improvement is of significantimportance to growers, who rely upon the regenerative ability ofsuckers, in order to guarantee subsequent crops. The unique two-tonecolor of ‘PBBrasp1351’ is distinct, and therefore desirable, in contrastto that of the yellow-fruited male parent (yellow raspberries arealready in the commercial trade). All patented previous releases fromthis program, including ‘Pacific Deluxe’ (U.S. Plant Pat. No. 21,074),‘Pacific Royale’ (U.S. Plant Pat. No. 21,536) and ‘Pacific Majesty’(U.S. Plant Pat. No. 47,306) have red fruit color (as is standard forraspberries). This further indicates ‘PBBrasp1351’ as a unique variety.Thus, these characteristics help define ‘PBBrasp1351’ as a new anddistinct cultivar of primocane-fruiting raspberry. ‘PBBrasp1351’ may berecognized by its unique fruit color, high vigor, strong suckeringhabit, superior floricane budbreak, large broadly-conic berries ofpeach-yellow color and high gloss, and which consistently yield morethan existing varieties within the same program.

DETAILED DESCRIPTION

Note: statements of characteristics herein represent exemplaryobservations of the cultivar herein and will vary depending on time ofyear, location, annual weather, etc.

-   Cultivar name: ‘PBBrasp1351’.-   Classification:    -   -   Family.—Rosaceae.        -   Botanical name.—Rubus idaeus L.        -   Common name.—Raspberry.-   Parentage:    -   -   Female parent.—‘Pacific Gema’ (U.S. Plant patent application            Ser. No. 14/544,823, filed Feb. 24, 2015).        -   Male parent.—‘1108’ (unpatented). As noted above, the            present cultivar, ‘PBBrasp1351’ offers many advantages over            the red-fruited maternal parent, ‘Pacific Gema’, and the            yellow-fruited paternal parent ‘1108’. The most distinct            characteristic of ‘PBBrasp1351’ is the color, which is            unlike either parent. ‘PBBrasp1351’ has an intermediate            color, with peach-colored overtones and yellow-colored            undertones. Often, berries of ‘PBBrasp1351’ appear to be            two-tone, which is unique for raspberry. The unique color            offers significant advantages to marketers who seek methods            to distinguish commodity products. Average fruit size of            ‘PBBrasp1351’ is considerably larger than both parents.            Berries detach easily from the receptacle, which is similar            to parent ‘1108’, yet much easier than ‘Pacific Gema’.            Fruits of ‘PBBrasp1351’ are broadly-conic in shape (versus            the narrow conic shape of ‘Pacific Gema’ and ‘1108’). Yield            of ‘PBBrasp1351’ is also much greater than ‘Pacific Gema’            and ‘1108’, on average, due to its higher vigor and larger            fruit size. The ease of fruit detachment and improved yield            offers significant advantages to growers, who require fast            picking speeds and lighter fruit color, combined with            glossiness which helps to extend shelf life of the fruit (by            appearing to stay fresher for a longer period of time). The            larger, broadly-conic berries help growers fill baskets more            quickly, leading to increased harvest efficiency. Root            vigor, subsequent cane vigor, and floricane budbreak for            ‘PBBrasp1351’ is superior to ‘Pacific Gema’ and ‘1108’. In            contrast to the unpatented male parent ‘1108’, the present            invention is significantly greater in vigor, plant fitness            and offers larger fruit. In particular, the amount of            suckers that ‘PBBrasp1351’ produces is two-fold of its            paternal parent. This improvement is of significant            importance to growers, who rely upon the regenerative            ability of suckers, in order to guarantee subsequent crops.            The unique two-tone color of ‘PBBrasp1351’ is superior to            that of the yellow-fruited male parent.-   Growing location for the observations herein: Watsonville, Calif.,    USA.-   Time of year (season): Spring 2016 for floricanes; Summer 2016 for    primocanes.-   Age of plants used for this discussion: Crown age of about 2 years;    floricane age=18 months; primocane age=7 months.-   Age of plants used for the photographs in the figures: Crown age of    about 3 years and a cane age of about 4-8 months.-   Type of greenhouse covering or growing structure, or field: High    tunnel over field-grown plants.-   Light: Natural.
